[0021] 2. The damping cylinder, damping oil cylinder, and pneumatic-hydraulic damping cylinder in this utility model are existing devices on the market, which manufacturers can purchase directly. This facilitates the assembly of the inner and outer thigh fitness equipment. These devices offer smooth transmission, precise stopping, and low noise, making them convenient for users. The adjustable components allow users to flexibly adjust the damping of the damping device as needed. Since the damping device includes elastic and sliding components, its simple structure facilitates self-processing and production by manufacturers, reducing the production cost of the inner and outer thigh fitness equipment. Furthermore, the maximum training intensity of the inner and outer thigh fitness equipment can be changed by altering the elastic force of the elastic component, allowing for flexible production. The drive block and control block not only facilitate the adjustment of the sliding component by the adjustable component but also facilitate the connection and cooperation between the adjustable component and the sliding component during the use of the inner and outer thigh fitness equipment, making the adjustment and control of the inner and outer thigh fitness equipment convenient.

[0022] 3. In this utility model, the initial position of the swing arm is changed by installing the traction rope at different mounting positions. The structure is simple and convenient for users to adjust the initial position of the swing arm as needed, making it convenient for users to use. Since the traction rope fixing part has multiple fixing positions on the rack plate, it is convenient for users to flexibly adjust the initial position of the swing arm during movement as needed, making it convenient for users to use the inner and outer thigh fitness machine flexibly. Moreover, since the rack plate is provided with rack parts that mesh with the drive gears on the two swing arms respectively, this structure is conducive to the synchronous movement of the two swing arms, making it convenient for users to exercise both legs simultaneously.

Two sets of swing arms 3 are rotatably mounted on the frame 1, and a damping device 6 is provided on the frame 1. During the rotation of the swing arms 3, the damping device 6 can provide damping for the movement of the swing arms 3. A receiving space 111 is provided under the seat 2, and the damping device 6 is disposed in the receiving space 111. A drive gear 33 is provided on the swing arms 3, and a transmission component adapted to the drive gear 33 is movably mounted on the frame 1. A traction rope 5 is provided between the damping device 6 and the transmission component to control the rotation of the swing arms 3. The drive gear 33 can drive the damping device 6 to deform or move through the transmission component and the traction rope 5. The damping device can drive the two sets of swing arms 3 to open or close to each other through the traction rope 5 and the transmission component 4. In this structure, the swing arms 3 are... The drive gear 33 is connected to the transmission component. This structure facilitates a stable connection between the swing arm 3 and the transmission component. During use, the resistance arm of the swing arm 3 remains constant, preventing changes in the resistance arm of the swing arm 3 during exercise from affecting the training intensity of the inner and outer thigh exerciser. This makes it convenient for users to exercise. Manufacturers can reduce the resistance arm of the drive gear 33 and the swing arm 3, thereby reducing the maximum damping of the damping device 6 and its size. This helps reduce production costs and facilitates the mounting of the damping device 6 in the mounting bracket. Furthermore, the damping device 6 is located in the receiving space 111 under the seat 2, which helps reduce the volume of the inner and outer thigh exerciser, making it convenient for users to use the inner and outer thigh exerciser at home and facilitating its storage and transportation.

[0046] The damping device 6 described in this utility model can be a damping cylinder, a damping oil cylinder, or a pneumatic-hydraulic damping cylinder. A piston connected to the traction rope 5 is provided on the damping device 6. The damping device 6 provides damping for the movement of the piston, thereby providing damping for the movement of the traction rope 5, the transmission component, and the swing arm 3. The damping device 6 is also equipped with an adjusting component 7 for adjusting the damping during piston movement. Damping cylinders, damping oil cylinders, and pneumatic-hydraulic damping cylinders are commercially available devices that manufacturers can directly purchase and install in the accommodating space 111, facilitating the assembly of the inner and outer thigh fitness equipment. These devices offer smooth transmission, precise stopping, and low noise, making them convenient for users. The adjusting component 7 allows users to flexibly adjust the damping of the damping device 6 as needed. Since damping cylinders, damping oil cylinders, and pneumatic-hydraulic damping cylinders are all existing technologies and are used in fitness equipment, although not specifically shown in this utility model, those skilled in the art can implement this technical solution based on the description and existing technology.

[0047] The preferred damping device 6 in this invention includes an elastic element 62 and a sliding element 61. The traction rope 5 is connected to the sliding element 61. The elastic element 62 can provide damping for the movement of the swing arm 3 through the sliding element 61, the traction rope 5, and the transmission component. The elastic element 62 can drive the sliding element 61 to reset, and drive the swing arm 3 to reset through the traction rope 5 and the transmission component. This structure is simple, convenient for manufacturers to process and produce, and helps to reduce the production cost of the inner and outer thigh fitness equipment. In addition, the maximum training intensity of the inner and outer thigh fitness equipment can be changed by changing the elastic force of the elastic element 62, which facilitates flexible production by manufacturers.

[0048] The frame 1 is provided with a mounting cavity 131. The sliding member 61 and the elastic member 62 are both disposed in the mounting cavity 131. An adjusting member 7 is rotatably disposed on the frame 1. The sliding member 61 includes a driving block 612 slidably connected to the mounting cavity 131 and a control block 611 slidably connected to the adjusting member 7. The driving block 612 and the control block 611 are threadedly connected. The adjusting member 7 can drive the control block 611 to rotate and drive the driving block 612 to slide in the mounting cavity 131 through the threaded structure, thereby controlling the deformation of the elastic member 62. The arrangement of the driving block 612 and the control block 61 not only facilitates the adjustment of the sliding member 61 by the adjusting member 7, but also facilitates the connection and cooperation between the adjusting member 7 and the sliding member 61 during the use of the inner and outer thigh fitness machine, making the adjustment and control of the inner and outer thigh fitness machine convenient.

[0049] In this embodiment, an end cap 15 is detachably provided at one end of the mounting cavity 131. The end cap 15 allows the elastic member 62 and the sliding member 61 to be stably installed in the mounting cavity 131. The end cap 15 is provided with a rotating hole 151. The adjusting member 7 includes a driving disk 72 and a sliding rod 71. The sliding rod 71 is rotatably disposed in the rotating hole 151. The control block 611 is provided with a sliding cavity 613 adapted to the sliding rod 71. The sliding cavity 613 is an irregular hole. The sliding rod 71 can drive the control block 611 to rotate through the sliding cavity 613, and the sliding rod 71 can slide along the extension direction of the sliding cavity 613.

[0050] The drive block 612 is provided with a threaded hole 614, the control block 611 is threadedly connected to the threaded hole 614, and the side wall of the mounting cavity 131 is provided with a guide groove 132. The drive block 612 is provided with a guide protrusion 615 adapted to the guide groove 132. The adjusting member 7 controls the control block 611 to rotate, thereby causing the drive block 612 to slide along the guide groove 132 and causing the elastic member 62 to compress or extend.

[0051] In this invention, by changing the connection position of the transmission component 4, the swing arm 3 can be kept in an extended or closed state. When the swing arm 3 is kept in an extended state, the user's legs can control the swing arm 3 to move closer together and exercise. When the swing arm 3 is kept in a closed state, the user's legs can control the swing arm 3 to move closer together and exercise.

[0052] The transmission component 4 is provided with several mounting positions. The initial position of the swing arm 3 is different when the traction rope 5 is installed in different mounting positions. This structure is simple and makes it easy for users to adjust the initial position of the swing arm 3 as needed, which is convenient for users to use.

[0053] In this invention, the user can directly change the initial connection position between the transmission component 4 and the traction rope 5, or indirectly change the initial connection position between the transmission component 4 and the traction rope 5. Preferably, the transmission component 4 includes a rack plate 41 connected to the drive gear 33 and a traction rope fixing component 42 connected to the traction rope 5. The traction rope fixing component 42 has multiple fixing positions on the rack plate 41. By changing the fixing position of the traction rope fixing component 42 on the rack plate 41, the connection position between the traction rope 5 and the rack plate 41 can be changed, thereby indirectly installing the traction rope 5 in different installation positions and adjusting the initial position of the swing arm 3 during movement. This structure allows the user to flexibly adjust the initial or extreme position of the swing arm 3 as needed, making it convenient for the user to use the inner and outer thigh fitness machine flexibly.

[0054] The rack plate 41 is provided with rack portions 412 that mesh with the drive gears 33 on the two swing arms 3 respectively. This structure is conducive to the synchronous movement of the two swing arms 3, making it convenient for the user to exercise both legs simultaneously.

[0055] The initial position of the swing arm 3 described in this utility model is the position where the damping device 6 drives the swing arm 3 to reset when the inner and outer thigh fitness machine is not in use.

[0056] The traction rope fixing component 42 and the rack plate 41 are slidably connected to the frame 1, or the traction rope fixing component 42 is slidably connected to the rack plate 41. The rack plate 41 is provided with a plurality of positioning holes 411 at intervals. The traction rope fixing component 42 is provided with positioning pins 43 that cooperate with the positioning holes 411. By controlling the positioning pins 43 to cooperate with different positioning holes 411, the traction rope fixing component 42 is fixed at different positions on the rack plate 41, thereby changing the initial position of the swing arm 3 during movement. The structure of the positioning holes 411 and the positioning pins 43 is simple, which is convenient for manufacturers to produce and process, and easy for users to adjust and control.

[0057] Preferably, the positioning pin 43 is provided with a guide surface 431, and the positioning pin 43 is guided through the guide surface 431 into the positioning hole 411. The traction rope fixing member 42 is provided with a mounting hole for installing the positioning pin 43.

[0058] In this invention, when the user needs to perform leg-opening training, the control positioning pin 43 engages with a positioning hole 411 and the two swing arms 3 move closer to each other in the initial state of the inner and outer thigh fitness device. When the user needs to perform leg-closing training, the control positioning pin 43 engages with a positioning hole 411 and the two swing arms 3 move further apart in the initial state of the inner and outer thigh fitness device.

[0059] The frame 1 described in this utility model is provided with a slide groove for installing transmission components. A guide wheel 14 is rotatably arranged on one side of the slide groove. The traction rope 5 drives the transmission component to abut against the guide wheel 14. The slide groove facilitates the stable installation of the transmission component, while the guide wheel 14 helps to reduce the friction on the transmission component during use, which helps to reduce the noise during the use of the inner and outer thigh fitness machine, and avoids the transmission component and frame 1 from being severely worn after long-term use, which would affect the normal use of the inner and outer thigh fitness machine.

[0060] Preferably, two sets of guide wheels 14 are rotatably arranged on one side of the chute. The two sets of guide wheels 14 are respectively arranged on both sides of the traction rope 5 along the extension direction of the chute. The two sets of guide wheels 14 can guide the traction rope 5 to swing towards both ends of the chute. The two sets of guide wheels 14 arranged on both sides of the traction rope 5 make it easy for the user to control the swing arms 3 to move closer or further apart, which is convenient for the user to use flexibly.

[0061] In this embodiment, the slide groove includes a first slide groove 121 and a second slide groove 122. The rack plate 41 and the traction rope fixing member 42 are slidably disposed in the first slide groove 121 and the second slide groove 122, respectively. The guide wheel 14 is rotatably disposed in the second slide groove 122 and abuts against the traction rope fixing member 42. The first slide groove 121 is provided with hinge rods 123 on both sides, and a through groove 124 is provided between the first slide groove 121 and the hinge rods 123. The swing arm 3 is provided with hinge holes 34 that are adapted to the hinge rods 123. The rack plate 41 is provided with rack portions 412 on both sides. The drive gear 33 passes through the through holes and meshes with the rack portions 412.

[0062] The frame 1 includes a main support 11, a seat 2 is detachably mounted on the main support 11, and a sliding seat 12 is detachably mounted on the main support 11. A sliding groove is disposed in the sliding seat 12, and a guide seat 13 is detachably mounted on the sliding seat 12. A mounting cavity 131 is disposed in the guide seat 13. A first wire groove 133 is disposed at the bottom of the mounting cavity 131, and a second wire groove 125 is disposed on the side wall of the second sliding groove 122. The traction rope 5 passes through the first wire groove 133 and the second wire groove 125 and connects the sliding member 61 to the transmission member.

[0063] The frame 1 described in this utility model is provided with a horizontally rotatable leg rest 32. The leg rest 32 includes an L-shaped support part 321 and a baffle 322. The support part 321 can support the user's legs, and the user's legs can rest against the baffle 322 to drive the swing arm 3 to rotate.

The L-shaped support part 321 and baffle 322 not only facilitate the support of the legs by the leg rest 32, but also make it convenient for the user to control the rotation of the swing arm 3 by the leg rest 32. In addition, the leg rest 32 is also convenient for users with different leg sizes, avoiding the situation where the user's legs cannot be placed on the support part 321 due to the leg size being too large, thus making it convenient for the user.

[0064] In this embodiment, the bottom of the support part 321 is provided with a hinge sleeve 323, which is rotatably connected to the swing arm 3.

[0065] Since people's feet move unconsciously when they exert force with their legs, it is preferable that the swing arm 3 is provided with a foot pedal 31. The middle side of the foot pedal 31 extends to form a hinge shaft 311 that is rotatably connected to the swing arm 3. The foot pedal 31 can swing back and forth around the hinge shaft 311. The foot pedal 31, which can swing back and forth around the hinge shaft 311, facilitates flexible support for the user's feet and makes it convenient for the user to use.

[0066] In this embodiment, both foot pedals 31 are provided with buffer pads 312. When the two swing arms 3 come close to each other, the buffer pads 312 can collide with each other, thereby avoiding the collision between the foot pedals 31, swing arms 3 and leg rests 32, and avoiding the noise or damage to the foot pedals 31, swing arms 3 and leg rests 32.

[0067] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
